OBJECTIVETo determine the tricuspid annular plane systolic excursion (TAPSE) using M-mode echocardiography, and to evaluate the right ventricular systolic function in patients with pneumoconiosis.
METHODSOne hundred and eighty-three patients with pneumoconiosis were enrolled as subjects, and one hundred and ninety-nine healthy volunteers were used as controls. According to the types of ventilation dysfunction, patients were divided into four groups: normal type, obstructive type, restrictive type, and mixed type. In the apex four-chamber sections, the displacement of tricuspid annular plane on the right ventricular free wall side was measured from end-diastole to end-systole using M-mode echocardiography.
RESULTSThe average TAPSE in the pneumoconiosis group was significantly lower than that in the control group (18.61 ± 3.08 vs 22.38 ± 3.03 mm, P < 0.01). Along with the progression of pneumoconiosis, the TAPSE values in patients with stage I, II, and III pneumoconiosis were significantly decreased compared with those in the control group (P < 0.01). The TAPSE values in patients diagnosed with normal, obstructive, restrictive, and mixed types of pneumoconiosis in pulmonary function tests were all significantly lower than those in the control group (P < 0.01). Among all patients, patients with mixed type of pneumoconiosis had the most significant reduction in the TAPSE.
CONCLUSIONThe TAPSE is substantially decreased in patients with pneumoconiosis and further decreased along with the progression of pneumoconiosis. Measurement of the TAPSE is an easy way to evaluate the right ventricular systolic function in patients with pneumoconiosis.

We report a 66-yr-old male patient who developed tricuspid regurgitation secondary to internal cardiac massage. After uneventful off-pump coronary artery bypass surgery, the subject experienced cardiac arrest in the intensive care unit. External cardiac massage was initiated and internal cardiac massage was performed eventually. A transesophageal echocardiography revealed avulsion of the anterior papillary muscle and chordae to the anterior leaflet after successful cardiopulmonary resuscitation. Emergency repair of the papillary muscle was performed under cardiopulmonary bypass.

3.Ebstein's anomaly with refractory right-sided heart failure and leg ulcers: a case report.
Journal of Southern Medical University 2015;35(2):312-314
Ebstein malformation is a congenital heart disease characterized pathologically by displacement of the septal leaflet of the tricuspid valve towards the apex of the right ventricle of the heart. Hypoplasia, dysfunction of the right ventricle and tricuspid regurgitation cause an increased volume load of the right heart and result in the clinical manifestations of chest tightness, shortness of breath and fatigue after activities, palpitation, cyanosis and heart failure. We report a case of Ebstein's anomaly with refractory right heart failure and leg ulcers.

OBJECTIVETo evaluate the surgical treatment of tricuspid valve disease combined with cardiac cachexia.
METHODSSeven patients with heavy tricuspid valve disease combined with cardiac cachexia underwent tricuspid valve replacement. Heart function and nutrition status were improved in the perioperative period.
RESULTAll operations were performed successfully, but one patient died of heavy heart failure postoperatively. The mean follow-up length was 32 months, all patients had good heart function except one with minor right heart function failure.
CONCLUSIONProsthetic heart valve replacement is an effective treatment for patients with serious tricuspid valve disease combined with cardiac cachexia. The perioperative nutrition support and heart function improvement are important in the treatment process.

PURPOSETo evaluate and compare the effects of heart rate on conduction velocity in the cavotricuspid isthmus (CTI) and septum in patients with and without typical atrial flutter (AF) using electro-anatomic mapping (EAM) of the right atrium (RA).
METHODSTen patients (age 53+/-10 yrs, 7M/3F) with AF and 13 patients (age 51+/-11 yrs, 5M/8F) with atrioventricular nodal reentrant tachycardia (AVNRT) underwent conventional electrophysiological study, electro-anatomic mapping and radiofrequency ablation. Using EAMs obtained during coronary sinus pacing at pacing cycle length (PCL) 600 ms, 400 ms, and 300 ms, we evaluated conduction velocities in the CTI and septum of RA in 10 patients with AF and compared EAMs to 13 patients with AVNRT to determine whether the conduction slowing required to maintain AFL was related to changes in volume alone or altered RA electrophysiology.
RESULTSConduction velocities in CTI and septum were significantly slower at all PCL when AF was compared to AVNRT (*P<0.05). Additionally, in the AF group, septal conduction velocities were slower at PCL 600 ms and 400 ms, but not at 300 ms compared to CTI (*P<0.05). In AF, during PCL 300, conduction in CTI slowed significantly compared to PCL 600 and 400 ms such that there was no difference between CTI and septum at PCL 300.
CONCLUSIONSThere is slower conduction in the septum compared to the CTI in all patients. However, in patients with AF, there is significant slowing of conduction in the CTI and septum as well as decremental rate-dependent slowing of conduction in the CTI. These findings indicate that in addition to RA enlargement, changes in atrial electrophysiology distinguish AF patients from patients with AVNRT.

We evaluated long-term results of De Vega annuloplasty measured by cylindrical sizers for functional tricuspid regurgitation (FTR) and analyzed the impact of measured annular size on the late recurrence of tricuspid valve regurgitation. Between 2001 and 2011, 177 patients (57.9+/-10.5 yr) underwent De Vega annuloplasty for FTR. Three cylindrical sizers (actual diameters of 29.5, 31.5, and 33.5 mm) were used to reproducibly reduce the tricuspid annulus. Long-term outcomes were evaluated and risk factor analyses for the recurrence of FTR > or =3+ were performed. Measured annular diameter indexed by patient's body surface area was included in the analyses as a possible risk factor. Operative mortality occurred in 8 patients (4.5%). Ten-year overall and cardiac death-free survivals were 80.5% and 90.8%, respectively. Five and 10-yr freedom rates from recurrent FTR were 96.5% and 93.1%, respectively. Cox proportional hazard model revealed that higher indexed annular size was the only risk factor for the recurrence of FTR (P=0.006). A minimal P value approach demonstrated that indexed annular diameter of 22.5 mm/m2 was a cut-off value predicting the recurrence of FTR. De Vega annuloplasty for FTR results in low rates of recurrent FTR in the long-term. Tricuspid annulus should be reduced appropriately considering patients' body size to prevent recurrent FTR.

OBJECTIVETo observe the relationship between preoperative pulmonary artery pressure and postoperative right ventricular function in heart transplant patients.
METHODA total of 54 heart transplant patients were divided to two groups: group I (n = 34): preoperative pulmonary arterial systolic pressure (sPAP) > or = 45 mm Hg (1 mm Hg = 0.133 kPa) [(60 +/- 12) mm Hg]; group II (n = 20): sPAP < 45 mm Hg [(25 +/- 9) mm Hg]. Cardiac index (CI), pulmonary circulation resistance (PVR) and CVP were measured preoperatively and up to 60 hours post operation by Swan-Ganz catheter. The extent of tricuspid regurgitation at preoperation and 3, 7, 14, 21, 30 days post operation was evaluated by bedside echocardiography. Postoperative pulmonary hypertension was treated by diuresis, nitrates, Ilomedin 20 and hemofiltration (CRRT).
RESULTAll patients survived the operation. Preoperative PVR was significantly higher in group I patients than that of group II patients [(358 +/- 150) dyn x s(-1) x cm(-5) vs. (140 +/- 68) dyn x s(-1) x cm(-5), P < 0.01]. Right heart insufficiency early post operation was more often in group I patients than that in group II patients (70.6% vs. 35.0%, P < 0.05). The PVR was higher and tricuspid regurgitation extent severer in group II than group I early post operation and were similar 30 days post operation.
CONCLUSIONPost operative right heart insufficiency was associated to preoperative pulmonary hypertension in heart transplant patients.

OBJECTIVE: To assess perfusion patterns on a dual-energy pulmonary CT angiography (DECTA) of pulmonary hypertension (PHT) with variable causes and to assess whether the extent of perfusion defect can be used in the severity assessment of PHT. MATERIALS AND METHODS: Between March 2007 and February 2011, DECTA scans of 62 consecutive patients (24 men, 38 women; mean age, 58.5 +/- 17.3 [standard deviation] years; range, 19-87 years) with PHT were retrospectively included with following inclusion criteria; 1) absence of acute pulmonary thromboembolism, 2) maximal velocity of tricuspid regurgitation jet (TR Vmax) above 3 m/s on echocardiography performed within one week of the DECTA study. Perfusion patterns of iodine map were divided into normal (NL), diffuse heterogeneously decreased (DH), multifocal geographic and multiple peripheral wedging patterns. The extent of perfusion defects (PD), the diameter of main pulmonary artery (MPA) and the ratio of ascending aorta diameter/MPA (aortopulmonary ratio, APR) were measured. Pearson correlation analysis was performed between TR Vmax on echocardiography and CT imaging parameters. RESULTS: Common perfusion patterns of primary PHT were DH (n = 15) and NL (n = 12). The perfusion patterns of secondary PHT were variable. On the correlation analysis, in primary PHT, TR Vmax significantly correlated with PD, MPA and APR (r = 0.52, r = 0.40, r = -0.50, respectively, all p < 0.05). In secondary PHT, TR Vmax significantly correlated with PD and MPA (r = 0.38, r = 0.53, respectively, all p < 0.05). CONCLUSION: Different perfusion patterns are observed on DECTA of PHT according to the causes. PD and MPA are significantly correlated with the TR Vmax.
