Angioplasty of unusually large coronary arteries using the hugging balloon technique via a single guiding catheter.

Unusually large native coronary arteries, in particular those supplying expansive regions of myocardium, may not be adequately dilated using currently available coronary angioplasty catheters. The "hugging balloon" technique, in which two dilatation catheter balloons are simultaneously inflated side-by-side, has been previously described for lesions in large saphenous vein grafts using the double guiding catheter (and dual entry site) technique. With the development of large lumen guiding catheters and lower profile dilatation catheters, we report the initial use of the hugging balloon technique via a single guiding catheter in oversized native coronary arteries.

Tetralogy of Fallot in the elderly.

Tetralogy of Fallot was first diagnosed during life in this patient at the age of 61 years. He represents one of the oldest reported patients with this congenital heart anomaly. This report presents a case of a previously undiagnosed patient with tetralogy of Fallot.

Cardiac rhythm disorders complicating coronary arterial spasm.

Practically every known form of arrhythmia may complicate vasospastic ischemia. Of special importance are sinus node arrest and ventricular fibrillation. The high incidence of arrhythmia in this syndrome may be related to the usually severe profound ischemia or to the sudden massive reperfusion; both can frequently characterize transient severe segmental spasm of an artery without pre-existing stenosis. Nitrates and calcium channel blockers may be effective in the control of vasospasm-induced arrhythmia, but other traditional antiarrhythmic agents and pacemaker treatment may be required in some patients.

Pulmonic valvular stenosis: clinical-hemodynamic correlation and surgical results.

Sixty-six patients with pulmonic valvular stenosis were evaluated by cardiac catheterization and cine-angiography over the past four years in a recently established cardiovascular center in Syria. Patients were divided according to severity of pressure gradient across the pulmonic valve into three groups: Group I (25 patients) had gradients below 50 mm. Hg, Group II (14 patients) had gradients between 50 and 100 mm. Hg, and Group III (27 patients) had gradients exceeding 100 mm. Hg. Clinical symptoms and signs including dyspnea on exertion, palpitation, cyanosis, and characteristics of the murmur and the pulmonic second sound were correlated with severity and grouping along with electrocardiographic and radiographic findings. Valvulotomy was carried out in 23 patients (35%). Short term clinical results were excellent in 19 patients, but long term course of the non-operated and post-operative cases is yet to be established.

Surgical salvage of heart rupture: report of two cases and review of the literature.

Two patients who sustained cardiac rupture complicating recent myocardial infarction were salvaged by expeditious diagnosis and surgical treatment. The cases of 9 other similar patients have been reported in the English-language literature. The cases of these 11 patients were reviewed in an attempt to find common clinical, pathological, and therapeutic features that might have been instrumental in the successful outcome of this usually fatal complication.

Combined supravalvular aortic stenosis and hypertrophic subaortic stenosis: coexistence or association?

A 19-year-old male was found to have combined supravalvular aortic stenosis and hypertrophic subaortic stenosis. Two possible hypotheses with supportive evidence in the literature may explain this association: (1) long-standing fixed supravalvular aortic stenosis may result in secondary hypertrophic subaortic stenosis, and (2) infantile hypercalcemia, a condition closely related to supravalvular aortic stenosis, may also be involved by continuous inotropic stimulation in the pathogenesis of muscular hypertrophy and subaortic stenosis of the left ventricle. We tend to favor the second theory in light of recent evidence in the literature.

Hypoplasia of descending aorta as a rare cause of hypertension. A report of 5 cases.

Five cases of hypoplasia of the descending thoracic and/or abdominal aorta as a rare cause of hypertension are presented. Similarities and dissimilarities between this lesion and classical coarctation of the aorta are discussed. Management of the resulting hypertension is usually medical, as surgical therapy is extremely difficult due to the diffuse involvement of the entire aorta and its branches.

Mitral stenosis with severe pulmonary hypertension.

Consecutive catheterizations in 512 patients with mitral valve disease revealed 85 cases of mitral stenosis with systolic pulmonary artery pressures equal to or in excess of 100 mm Hg. Forty-four patients (51.8%) were in New York Heart Association functional Class IV; 30 (35.3%) were in Class III; and 11 (12.9%) were in Class II. Symptoms related to pulmonary capillary hypertension were prominent in 48 patients (56.5%) while the remaining patients showed signs of low cardiac output syndrome. Forty patients underwent surgery: mitral commissurotomy was performed in 26 patients; mitral valve replacement in 10 patients, and double valve replacement in four patients. Nitroprusside was infused into the pulmonary artery in six patients with severe perioperative low cardiac output; four of these patients survived. The overall operative mortality was 15% (six patients). Good long-term results were achieved in 30 cases.

Hypocalcemic cardiomyopathy.

Two patients with cardiomegaly and congestive heart failure were found to be grossly hypocalcemic secondary to previously undiagnosed hypoparathyroidism. The cardiac failure was refractory to digitalis preparations and diuretics but responded dramatically when specific therapy restored the serum calcium to normal. The mechanism of congestive heart failure in hypocalcemia is discussed, and their association constitutes one form of reversible cardiomyopathy which should be kept in mind when a patient fails to respond to conventional antifailure therapy.

Continuous precordial murmur due to congenital fistula between the femoral artery and the superior vena cava.

An unusual case of arteriovenous communication between the left inferior epigastric artery, a branch of the femoral artery, and the superior vena cava is presented. The communication caused a continuous murmur at the lower parasternal area and was responsible for a significant left-to-right shunt. Surgical treatment, which consisted of ligation of the aberrant artery at its origin, was followed by disappearance of the precordial murmur.

Atrioventricular and intraventricular conduction in hyperkalemia.

Twelve patients exhibited electrocardiographic evidence of fascicular block during hyperkalemia. Isolated left posterior hemiblock occurred in four, isolated left anterior hemiblock in two, right bundle branch block with left anterior hemiblock in two, right bundle branch block with left posterior hemiblock in one, left bundle branch block with abnormal left axis deviation in two and advanced atrioventricular block in one. In all seven patients with sinus rhythm the P-R interval shortened after correction of hyperkalemia. Electrophysiologic studies using His bundle recording and atrial pacing in one patient revealed intraatrial conduction delay and marked prolongation of conduction time in the His-Purkinje system. It is concluded that conduction defects in the specialized intraventricular conduction system are common in hyperkalemia and result in electrocardiographic patterns of fascicular block.

Midsystolic clicks originiating from tricuspid valve structures: a sequela of heroin-induced endocarditis.

In two patients who had been heroin users, loud midsystolic clicks developed during infective endocarditis involving the tricuspid valve. The sounds were loudest along the left sternal border, exhibited an increase in intensity during inspiration and were associated with right atrial gallop sounds and with murmurs of tricuspid regurgitation. This constellation of clinical events suggests that the midstystolic clicks emanated from tricuspid valve structures as a result of disordered function of the chordae tendineae. Prolapse of the tricuspid valve has recently been demonstrated angiographically to accompany similar abnormalities of mitral valve motion in certain patients with the click-murmur syndrome. The participation of the tricuspid valve in the generation of the auscultatory finding is unclear, but the cases herein reported suggest that the tricuspid valve is capable of producing these findings.
